BAIL-JOINT.

Specification of Letters Patent.

Patented June 26. 1906.

Application filed April 2a, 1906. at; 314,237.

zen of the United States, residing at Greencastle, in the county of Putnam and State of Indiana, have invented certain new and useful Improvements in Rail-Joints,of which the following is a specification.

The present invention has for its primary object to provide an improved rail-joint by means of which adjacent rail-sections can be readily connected in such a manner as to be securely held against any relative movement, either in a vertical or horizontal direction.

A further object is to construct the joint in a peculiar manner, so that the continuity of the tread portion will not be broken by the ezlrpansions and contractions which take ace.

p For a full description of the inyention and the merits thereof and also to acquire aknowledge of the details of construction of the means for effecting the result reference is to be had to the following description and accomp anying drawings, which- Figure 1 is a pers ective view of the improved rail-joint. 'g. 2 is a vertical longi: tudinal sectional view through the same. Fig. 3 is a vertical sectional view. Fig. 4 is a detail perspective view of the rail ends when detached, and Fig. 5 is a horizontal longitudinal sectional view through the joint.

Corres ending and like parts are referred to in the f0 0 description and indicated in all the views 0 the drawings by the same reference characters. r

The numerals 1 and 2 designate the abutting ends of two rail-sections, which maybe of any conventional form and areshown as having a standard-section. The web portions of the rail ends are enlarged at 3, so as to corre- V spond vap roximatel in thickness. to the width of e treads o the rails. A tenon 4 of approm'mately rect ar shape projects outwardly from the e ar ed portion 3 of the rail end 1, and the enlarged portion of the web of the rail end 2 is provided with a recess 5, adapted to receive the tenon 4. The upper portion of the end 1 is formed with a V- shaped tongue or projection 6, which is spaced from the tenon 4 and which forms a continuation of the tread of the rail. A de pression 7, corres on in sha e ,to the tongue 6, is forme in the ead of t e rail-section 2.

In order to form a rigid connection between the two rail ends, a bolt 8 is employed, which passes through corresponding openings 9 in the opposite sides of the recess 5 and an ope 10 in the tenon 4, which registers with e openings 9 when the rail ends are brought together into normal osition. It will be observed that the opemngs 9 in the sides of the recess 5 are elongated, so that the bolt 8 has a slight play, which\ enables the rails to contract and expand inthe usual man ner. Attention is called to the fact that the portion ofwthe bolt 8 adjacent the head is orm 'd with wings 1 1 and that the ends of the openings 9 adjacent the end-of the rail-sectlon 2 have an angular formation and are ada ted to engage with the wings 11 to hold the olt 8 against turning. It may be found desirable under certain conditions, as when the joint occurs between two ties, to employ a chair 12 of the typeshown, which comprises a base-plate having the longitudinal edges bent upwardly to embrace the flanges of the rails. Owing to the fact that the tongue 6 hasa V-sha ed formation, it will be apparent that the s ht movements of the tongue within the depression 7, due to the expansions and contractions of the rails, will not be sufficient to break the continuity of the tread.

Having thus described the invention, what is claimed as new is In a rail-joint, the combination of two abutting rail ends, the webs of the rail ends being enlarged at the joint so as to correspond inthickness to the width of the tread, a tenon of approximately rectangular formation projecting from the web portion of one of the rail ends and fitting in a corresponding recess in the web portion of the opposite rail end, a V-shaped tongue pro'ecting from the head of one of the rail ends and spaced from the before-mentioned tenon, the head of the opposite rail-section being formed with a V-shap ed '2 & tomes de ressio'n for the ratio ion of the toIi e, s on b e stein elon md to ermit ans 2. bolt assiiig thgongh ooi'responiihg o th yfis siwind soil-sa a of th rails. 1o openings in t e sidesof the before-mentions testimon whereof I afiix my signature recess m the. web of one of the reii-seotidns in plesenio'e of we witnesses.
